2.1 Spool Function Selection – The Most Important Decision

The KSO-G02 offers a wide range of spool configurations. Choosing the wrong one means the valve will not behave as your system requires when the power is removed. Here is a practical selection guide:

How to choose: If your cylinder must hold its position when the valve de-energizes - for example, a clamping fixture on a machining center - choose 2BA (2-position, all ports closed). If your cylinder must return to a defined position on power loss, choose a spring-offset spool (2BD or 2BP). If you need mid-position holding in a 3-position circuit, choose 4CD.

2.2 Pressure and Flow – 35 MPa / 100 L/min in a CETOP 3 Body

The KSO-G02 delivers 35 MPa maximum operating pressure and 100 L/min maximum flow - performance that exceeds most CETOP 3 solenoid valves on the market.

What this means for your system design: You can use a smaller manifold block (CETOP 3 instead of CETOP 5) for the same hydraulic power, reducing manifold weight and cost. The high allowable back pressure (17.5 MPa) also means the valve can tolerate return-line pressure spikes without malfunction - critical in systems where multiple actuators share a common return line.

2.3 Voltage Options – Match the Coil to Your Control System

The KSO-G02 is available in a full range of AC and DC coil voltages. The voltage code is the last character group in the model number:

Coil connection options include terminal box type (standard) and DIN connector type. The terminal box type includes an earth terminal for CE compliance and an integrated surge killer for electrical protection.

2.4 IP65 Protection – Built for Harsh Industrial Environments

The KSO-G02 features a dust-proof and waterproof construction that meets IEC Pub529 IP65 ingress protection standards. This means:

Dust cannot enter the solenoid coil or terminal area

Water spray from any direction will not cause malfunction

Suitable for CE-compliant equipment in European markets

Practical benefit: In machine shops where coolant mist and metal chips are present, or in outdoor hydraulic power units exposed to rain and wash-down, the IP65 rating eliminates the need for additional enclosure protection. The valve can be mounted directly on the manifold without a protective cabinet.

2.5 Cross-Reference Compatibility – Drop-In Replacement for Major Brands

The KSO-G02 is designed to the CETOP 3 / NG6 / NFPA D03 standard mounting interface. This means it will bolt directly onto any manifold machined for this standard. More importantly, the spool functions and port patterns are cross-compatible with major competing brands:

What this means for you: If you are replacing a Yuken DSG-01, a Nachi SS-G01, or a Parker D1VW valve on an existing machine, the KSO-G02 equivalent spool function will bolt directly onto the same manifold and perform the same function. Confirm the spool function code mapping before ordering.

2.6 Low-Wattage Coil Option – Drive Directly from PLC Output

For systems controlled by programmable logic controllers (PLC), the KSO-G02 is available with a low-wattage coil (DC:5W or AC:12W). The low current requirement allows the valve to be driven directly from a programmable sequence controller output without an intermediate relay.

Practical benefit: Fewer components in the control cabinet, simpler wiring, reduced panel space, and one less failure point per valve. For systems with multiple solenoid valves, the cumulative savings in relays and wiring can be significant.
